DiG-bench Tests AI Discovery in Games
๐กSee how AI agents perform when they must discover rules and objectives instead of following known instructions.
โก 30-Second TL;DR
What Changed
The benchmark contains 70 independent games, each represented by a short string with unique transformation rules.
Why It Matters
DiG-bench shifts evaluation beyond memorization and fixed-answer tasks toward open-ended discovery under unknown objectives. It could help researchers measure whether agents genuinely experiment, form hypotheses, and generalize rules rather than merely execute familiar patterns.
What To Do Next
Evaluate your agent on the 21 public DiG-bench games and log its experiments, hypotheses, and rule revisions instead of measuring only final success.
Key Points
- โขThe benchmark contains 70 independent games, each represented by a short string with unique transformation rules.
- โขAgents must infer both the game rules and unknown level-specific win conditions through interaction and experimentation.
- โขThe seven difficulty tiers range from routinely solvable tasks to challenges for leading agentic systems.
- โขAll games were solved by at least one human on the first attempt, supporting their use as discovery-oriented evaluations.
- โขTwenty-one games are publicly available, while the remaining games are held privately to prevent benchmark overfitting.

๐ Enhanced Key Takeaways
- โขDiG-bench is designed to address the 'generalization gap' in current LLM-based agents, which often struggle with out-of-distribution rule discovery compared to memorized patterns.
- โขThe benchmark utilizes a formal language representation for game rules, allowing researchers to measure the sample efficiency of agents as they interact with the environment.
- โขThe evaluation framework specifically tracks 'discovery trajectories,' measuring how many interactions an agent requires to transition from random exploration to optimal policy execution.
- โขThe reserved test set is managed via a blind evaluation server, preventing data contamination that has plagued previous benchmarks like ARC-AGI or GSM8K.
- โขThe project emphasizes 'black-box' discovery, meaning agents are not provided with the underlying code or logic of the games, forcing them to rely solely on state-transition observations.

๐ ๏ธ Technical Deep Dive
- The benchmark uses a state-space representation where each game is defined by a set of transition functions mapping (state, action) pairs to new states.
- Agents interact via a standardized API that returns observations as symbolic strings, minimizing the need for complex visual processing and focusing on logic.
- The system employs a 'hidden rule' architecture where the win condition is decoupled from the transition rules, requiring agents to maintain separate hypotheses for mechanics and goals.
- The evaluation metric is primarily based on 'discovery steps'โthe number of environment interactions required to achieve a 100% success rate on a previously unseen game instance.
